Construction planning through to completion can be tricky to coordinate, especially within an urban area, which can present a range of complications. Building proximity, tall building heights, complex building structures, and densely populated areas are just a few challenges that can make it particularly difficult to consider traditionally heavy or large-sized materials when roofing or re-roofing a building.

When it comes to commercial roofing, the options are plentiful—but not every option is suited for every building. Each building has unique needs that factor into which types of roofing may be suitable for a given project. Here is an overview of what goes into a commercial roof as well as the material options available.

When designing and specifying a low-slope roofing system, it's important to consider the roof system's ability to resist external fire. Now, there are products available that can provide the necessary fire rating for your roofing system while also helping your building achieve credits toward LEED certification.

When part of your building's roof has a flat section covered with a traditional low-slope roofing material (such as single-ply or modified bitumen membranes), while another part of the building's roof is steep-slope and covered with asphalt shingles, we refer to that as a "mixed roof."
